Answer: Yes they are
Step-by-step explanation:
Answer:
(7,9)
Step-by-step explanation:
7x - 8y = -23
7x - 7y = -14
Solve the equation for 7x
7x - 8y = -23
7x = -14 + 7y
Substitute the given value of 7x into the equation 7x - 8y = -23
-14 + 7y - 8y = -23
solve the equation for y
y = 9
substitute the given value of y into the equation 7x = -14 + 7y
7x = -14 + 7(9)
solve the equation for x
x = 7

Answer:
9 hours
Step-by-step explanation:
Abe's charge = Gabe's charge
$130+($70/hr)h = $40+($80/hr)h
Then 130 + 70h = 40 + 80h, or
90 = 10h, or h = 90/10 = 9
When 9 hours have passed, the amount charged by each person will be temporarily equal.
